LEIGHTON MACDONALD PERVEIL, OF MANHEIM, PENNSYLVANIA.

BAROMETRICAL ROSE.

v SPECIFICATION forming part of Letters Patent No. 456,498, dated July21, 1891.

Application filed August 15, 1890- Serial No. 362,075. (No specimens.)

To aZZ whom it may concern.-

Be it known that I, Lnrenron MACDONALD PERVEIL, a citizen of the UnitedStates, residing at Manheim, in the county of Lancaster and State ofPennsylvania, have invented a new and useful Barometrical Rose, of whichthe following is a specification.

My invention relates to weather-indicators, and has for its object toprovide a simple, attractive, inexpensive, and practical article thatwill be readily susceptible to all changes in the weather, correctlyindicate them, and at the same time, by its fanciful appearance, permituse as an article of ornamentation.

My invention consists of an artificial rose made of thin whitetissue-paper saturated in a solution of cobalt chloride and suitably setin relief Within a frame, and of further details of constructionhereinafter more fully described, illustrated in the drawings, andspecifically stated in the claims.

In the accompanying drawings, Figure 1 represents a plan View of aweather-indicator constructed in accordance with my invention. Fig. 2 isa transverse section.

Like letters indicate like parts in the figures.

A represents a rectangular frame constructed of any suitable materialand provided with any suitable ornamentation. A circular opening a isformed in the center of said frame and a backward boxed extension B, ofa smaller diameter than the diameter of the main frame, is securedthereto. A knob a, secured to the frame A, and a ring ta attached to theknob,-indicate means for hanging the article where it may be desired.

Within the casing formed by the frame A and extension 13 an artificialrose 0, saturated with a substance susceptible to changes in theatmosphere, is secured. The stem of the rose 0 and leaves 0 are placedwithin the aperture 1) of the boxing B, and are thereby firmly held inposition. A background D of crushed black tissue-paper sets thelightrose off in marked relief from the back of the frame. The rose by beingsecured within the extended boxing is thereby seated a considerabledistance from the surface of the frame A and thus protected fromaccidental injury and also given an attractive appearance.

The article is to be placed in the position usually occupiedbyathermometer, protected from sun, rain, and storm, and the colorsgiving indications are: blue, fair and dry; lilac, change; pink, dampand wet weather.

In preparing the rose for my article I first take a suitably-sized fiatvessel and level it. The solution of cobalt chloride is then poured intothe vessel to the depth of half an inch or more, in which the sheets ofwhite tissue-paper are well immersed. The sheets while wet are removedfrom the vessel and, not being allowed to drain, are spread on a glassplate and immediately dried by the sun or otherwise. After the tissuehas dried, which will be known by its deep-blue color, the sheets arecut in the proper form and shaped to an artificial rose or other flower.

Should the paper be allowed to drain, the tissue when dry would be foundto be unevenly coated and weak in color, Whereas by following thedescribed method an even coating and strong permanent colors are theresult. But this manner of preparing the flower is only a preference,andI do not claim either this method or the method of preparing the samein any other way, or the flower per se, but limit myself to the specificcombination of the article of manufacture as expressed.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

As an article of manufacture, an ornamental weather-indicator consistingof a rectangular frame provided with a central opening, an extendedboxing or casing inclosing said opening, a barometrical-flowerindicator, subject to the changes of weather by variations of color,secured within said frame and casing, and a background of crushedtissue-paper placed between said ornamental indicator and the rear faceof the inclosing casing to throw the ornament out in relief,substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.
